the current supply can be seen in the datasheet, which is about 10-15mA. Usually will work optimally if given a 5-15V. vcc, pin it to receive a DC voltage supply.Switching transistor serves to clamp the corresponding node to ground on the timing of certain

discharge, this pin is connected to an open collector transistor Q1 is connected to ground emitternya.

Satu timer dihasilkan frekuensi rendah dan frekuensi tinggi lain yang dihasilkan. Sebenarnya, suara genereted oleh kombinasi suara dari kedua IC 555. Kedua IC timer 555 digunakan sebagai multivibrators astabil.

threshold, this pin is connected to the positive input (comparator A) which will reset the RS flip-flop when the voltage on the capacitor from exceeding 2 / 3 Vc Rangkaian Sirine Polisi Sederhana Ini adalah sirkuit alarm polisi. Di samping adalah skema rangkaian sirine polisi dengan menggunakan 2 IC yang suaranya sangat memuaskan silahkan di coba semoga berhasil.

This pin can be left hanging, but to ensure the stability of the reference comparator A, usually associated with a capacitor of about 10nF to berorde pin groun

control voltage, this pin serves to regulate the stability of the reference voltage negative input (comparator A).

Normally this pin is connected directly to Vcc to prevent reset This pin is connected to a PNP-type transistor gate, so the transistor will be active if given a logic low.

reset, the pin that serves to reset the latch inside the IC to be influential to reset the IC work. Klakson Mobil,suara Klakson Mobil Polisi Mp3-tes Modul Sirine CJB100BDI 100watt (senken) + Speaker Yd100i 100watt Klakson Mobil,suara Klakson Mobil Polisi Mp3.

trigger, negative input from the lower comparators (comparator B) that maintain oscillation capacitor voltage in the lowest 1 / 3 Vcc and set RS flip-flop.

Ground, is the input pin of the source of the negative DC voltage RANGKAIAN PESAWAT RADIO TANPA BATERAI Sirine Patwal Sirine Polisi Sirine Strobo Strobo Dashboard Batu Permata Batu Permata Murah Batu Permata Jogja sirine patwal.
